I haven't done anything similar with groovy, but I think it should work more-or-less the same, since it's all CMake based. When I wanted to install OpenCV with CUDA, I did the process below. Note: I am a novice at building with CMake, so there are probably better ways of doing this.

1. Install OpenCV to a specific directory following the instructions on their website.

2. Create a CMakeModule folder within your working program directory, find a version of FindOpenCV.cmake to copy into that folder, then specify the path to OpenCV by adding the line:

   set(OpenCV_DIR "/directory/to/opencv2")

3. In your program's CMake file, add:

   SET(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${PROJECT_SOURCE_DIR}/CMakeModules/")

   find_package(OpenCV REQUIRED) include_directories(${OpenCV_INCLUDE_DIRS}) add_definitions(${OpenCV_DEFINITIONS}) MESSAGE(STATUS "OpenCV at: ${OpenCV_INCLUDE_DIRS}")

   <more code...&gt;<="" p="">

   target_link_libraries(executable_name ${OpenCV_LIBRARIES})

There might be some specifics that are incorrect, but I think the general idea should work.
